A few things I have observed:
1. (twice now) - I have sectors 100 % explored, all planets and wrecks explored, yet on the warp screen it shows 1 planet unexplored. Is it invisible??
2. Artifacts with strange effect. I had one that gave me a penalty for choosing both beneficial and negative effect... with no third choice, I am unable to identify it (I sold it to firax for quest so no longer have it...)
3. I have another artifact that has the negative effect of reducing suit oxygen. Before selling it, I had 416 oxygen. After, 368... seems like it was increasing oxygen.
4. Very frequently there are unreachable areas in both caves and on cave planets. Sometimes these areas have components too... :-(
In a related situation, at least 6 times I have had a component appear at the edge of a cave complex (edge of the walk-able part), yet be unable to pick it up (I was not carrying any other large item) - almost like it was in the wall.
